Sweet! I'm out. Unlike many other people in previous posts, I found the last puzzle quite easy. although puzzle 5, I think it was, with the 3x3 grid and putting the animals on it. That one I didn't understand at all.

For the 3x3, two rooms have images of the man, bird and camel with compass points, you can derive their positioning and placement for the grid from them.

For the final puzzle, it's like a map of the game. Each room has a glyph over the door that needs to match the large glyph on the final door (in the room with the cross-like puzzle). Rotate the corresponding areas to make the glyphs all line up the same. You can leave the puzzle to look in each room as you go, without having to redo the ones you have already gotten correct.

Totally needed clues for the 3x3 grid, still don't really know why the placement was the way it was...but I was able to understand the rest of it with some thinking. Nice room escape. This developer always does a nice job. Thanks, Bart!
